Why is the Paralax Slider not showing on the home page ?
I selected home page for location and the slides are on (default slides) but it is not showing.
At our end the slider is working fine on the WordPress latest version 4.4.2 (see: http://prntscr.com/9yuga3). Please confirm that you have Parallax slider enabled to the homepage under your Theme options -> Parallax Slider -> General.
I have defined a menu color and it was working until I updated from 4.4.1 to 4.4.2
At our end, on the latest version of WordPress the menu color is changing nicely from under Appearance -> Theme Options -> Styling -> Menu, as per shown here (see: http://prntscr.com/9yuj68).
As a side note, please make sure you are using a static homepage and postpage from under WordPress admin -> Settings -> Reading.
